I have a Google Chart (column-chart) showing a single dated (Jan-2010 = 2010-01-01) column - but the resulting column seems to run from 1-Jul-09 through to 1-Jul-10 (note this seems to change depending on the width of the screen); how can I fix this so that the column sits only on the 01-Jan-2010 date? (**Note, the dates/values are variable and can include one or hundreds of column values so we CANNOT simply hard code this or change the column type from 'date' to 'string').
var arr = eval("[[new Date(2010, 0, 1), 0,1]]");
var data = new google.visualization.DataTable();
data.addColumn('date', 'Dt');
data.addColumn('number', 'Open');
data.addColumn('number', 'Closed');
data.addRows(arr);
var options_stacked = {
isStacked: true,
height: 300,
colors: ['#111', '#a00'],
hAxis: {
slantedText: false,
format: 'd/MMM/yy',
},
legend: {
position: 'top',
},
vAxis: {
minValue: 0
}
};
var chart = new google.visualization.ColumnChart(document.getElementById('chart_div'));
chart.draw(data, options_stacked);
A demonstrator for this can be found on https://jsfiddle.net/Abeeee/d5fojtp2/34/
you can add custom ticks to ensure each column "sits" on the correct date.
the ticks option expects an array of values.
we can use DataTable method --> getDistinctValue(colIndex)
to return the date values from the data table.
var xTicks = data.getDistinctValues(0);
hAxis: {
slantedText: false,
format: 'd.MMM.yy', <---- changed from 'd/MMM/yy' to avoid line breaks
ticks: xTicks
},
see following working snippet...
function doTest() {
var arr = eval("[[new Date(2010, 0, 1), 0,1]]");
var data = new google.visualization.DataTable();
data.addColumn('date', 'Dt');
data.addColumn('number', 'Open');
data.addColumn('number', 'Closed');
data.addRows(arr);
var xTicks = data.getDistinctValues(0);
var options_stacked = {
isStacked: true,
height: 300,
colors: ['#111', '#a00'],
hAxis: {
slantedText: false,
format: 'd/MMM/yy',
ticks: xTicks
},
legend: {
position: 'top',
},
vAxis: {
minValue: 0
}
};
var chart = new google.visualization.ColumnChart(document.getElementById('chart_div'));
chart.draw(data, options_stacked);
}
window.addEventListener('resize', doTest);
google.charts.load('current', {
packages: ['corechart', 'bar']
});
google.charts.setOnLoadCallback(doTest);<script type="text/javascript" src="https://www.gstatic.com/charts/loader.js"></script>
